Support for deep inner classes in options-enumeration
-----------------------------------------------------
Key: STS-299
URL: http://mc4j.org/jira/browse/STS-299
Project: Stripes
Issue Type: Improvement
Components: Tag Library
Affects Versions: Release 1.4.1
Reporter: Andy
Assigned To: Tim Fennell
Priority: Trivial
Currently the options-enumeration tag supports enums in a single-level inner
class to be specified using dots ('.') only without dollars ('$'). (Refer to
STS-253)
So in the following, enum="xxx.enums.Outer.LevelOne" works, but
enum="xxx.enums.Outer.Inner.LevelTwo" does not. The latter enum can still be
specified as "xxx.enums.Outer$Inner$LevelTwo", which looks ugly.
It will be better if the tag allows any number of dollars to be specified as
dots.
package xxx.enums;
public class Outer {
public static enum LevelOne { ONE, TWO }
public static class Inner {
public static enum LevelTwo { THREE, FOUR }
}
}
One strategy would be to keep replacing the last (rightmost) dot with a dollar
until ReflectUtil.findClass works or until there are no more dots (at which
point, the original exception should be thrown). This code can be placed in a
utility class (ReflectUtil.findClass itself looks good) and reused in case
there are inner ActionBean classes to be specified in other tags (form, link,
url, useActionBean) :)
